A single-player basketball simulation game. Make trades, set rosters, draft players, and try to build the next dynasty, all from within your web browser. The game is implemented entirely in client-side JavaScript, backed by IndexedDB.

Basketball GM is NOT open source, but it is also not completely closed. Please see LICENSE.md for details.
If you just want to play the game, go to http://basketball-gm.com/. Instructions below are for developers who want to run a copy locally so they can make changes to the code.
If you want to contribute but get stuck somewhere, please contact me! I'm happy to help.

If you want to contribute code to Basketball GM, you must sign a contributor license agreement. There are separate forms for individuals and entities (such as corporations):
- Individual CLA (this is probably what you want)
- Entity CLA
Make a copy of the form, fill in your information at the bottom, and send an email to commissioner@basketball-gm.com with the subject line, "Contributor License Agreement from YOUR_NAME_HERE (GITHUB_USERNAME_HERE)".
All of the tooling used in development can be installed by simply installing npm and running
npm install
from within this folder.
Basketball GM uses the Browserify for JS minification and clean-css for CSS minification. To minify everything, run
npm run build
However during development, you probably would rather do
npm run watch-js
which will constantly look for changes in your JS files and recompile. Then for CSS files, if you go to Tools > Debug Mode (inside the game), it will use the raw uncompiled CSS files so you don't need to keep compiling them after each change.
To run the game locally, you need some way of running a web server to display the content. There are currently two ways to do it. It doesn't matter which you use as long as you can get it to run on your computer.
Run
npm start
and point your browser to http://localhost:3000/.
The mod_rewrite rules in .htaccess
can be used to make Apache run Basketball
GM. Everything should work if you point it at the build
folder with
mod_rewrite enabled. That's how it's done on play.basketball-gm.com.
ESLint is used to enforce some coding standards. It's mostly pretty standard Crockfordian stuff. To run ESLint on the entire codebase, run
npm run lint
Integration and unit tests are bunched together in the js/test
folder.
Coverage is not great. They can be run from the command line in Karma with
npm test
or manually within a web browser by running npm run build-test
(or
npm run watch-test
) and going to http://localhost:3000/test.
Basketball GM is a single-page app that runs almost entirely client-side by
storing data in IndexedDB. All the application code is in the js
folder.
Routes are set in js/app.js
. Most of the important stuff is in js/core
.
UI is ultimately driven by js/util/bbgmView.js
, a small UI layer I wrote on
top of Knockout which is used by all the views in the js/views
folder. Each
view also has a corresponding HTML file in the templates
folder. Adding a new
page is kind of a bitch. You need to explicitly include the template file in
js/templates.js
, and explicitly include the view in js/views.js
. Beyond
that, my best guidance is to copy from an existing page and use that as a
starting point.
For database access, I wrote a very thin Promises-based wrapper around IndexedDB called Backboard. Understanding how IndexedDB works is critical in any non-trivial work on Basketball GM.
Also, there is a global variable window.bbgm
which gives you access to many of
the internal functions of Basketball GM from within your browser.
Code should ideally be documented as described in the Google Closure Compiler documentation: https://developers.google.com/closure/compiler/docs/js-for-compiler. Google Closure Compiler itself isn't actually used for anything (yet).
If you want to contribute changes back to the project, first create a fork on GitHub. Then make your changes in a new branch. Confirm that the tests (hopefully including new ones you wrote!) and ESLint all pass. Finally, send me a pull request.
It's also probably a good idea to create an issue on GitHub before you start working on something to keep me in the loop.
Basketball GM's layout is currently based on Bootstrap 3.1.1 with the following options:
- @font-size-base set to 13px
Abbreviations of stats should be done like basketball-reference.com stat pages. For instance, "defensive rebounds" is "drb".
-
Make sure tests all pass (if necessary)
-
Write database upgrade code in
db.js
(if not already done piecemeal) -
Write key changes in
js/data/changes.js
-
Set version in index.html, CHANGES.md, and README.md, like http://semver.org/
-
Tag it in git like:
git tag -a v3.0.0-beta.2 -m '' git push --tags
The game runs equally well within a web browser and within Cordova (Android 4.4+). The codebase is designed to handle both situations (the main difference is absolute vs relative paths, governed by window.inCordova in index.html).
Warning: This hasn't been tested in a while and is probably broken by now.
